Conversion Functions

There are four types of conversions: coordinate (polar/rectangular), angular (degrees/radians), time (decimal/minutes–seconds), and unit (cm/in, °C/°F, l/gal, Kg/lb).

Coordinate Conversions

The function names for these conversions are y,x θ,r and θ,r y,x.

Polar coordinates (r,θ) and rectangular coordinates (x,y) are measured as shown in the illustration. The angle θ uses units set by the current angular mode. A calculated result for θ will be between –180° and 180°, between –πand π radians, or between –200 and 200 grads.

To convert between rectangular and polar coordinates:

1.Enter the coordinates (in rectangular or polar form) that you want to convert. The order is y šx or θ šr.

2.Execute the conversion you want: press zq(rectangular–to–polar) or {r(polar–to–rectangular). The converted coordinates occupy the X– and Y–registers.

3.The resulting display (the X–register) shows either r (polar result) or x (rectangular result). Press Zto see θ or y.
